Specification of Letters Patent.

Application filed January 16, 1908. Serial No. 411,134.

To all whom it may concern.'

Be it known that I, FREDERICK A. SAss, a citizen of the United States,residing at Chicago, in the county of Cook and State of Illinois, haveinvented certain new and useful Improvements in Devices for Embossingand Cutting Wooden Boards in Strips, of

which the following is a specification, reference being had therein tothe accompanying drawings.

My invention relates to devices for embossing and cutting wooden boardsin strips. Its object is to provide efficient and eXpeditious mechanismfor manufacturing wood molding and other ornamental stripping adapted toaccurately, evenly and economically strip and pattern in one operationan entire board with an accompanying economy of labor and machinery, agreatly increased capacity, and a better product than has hitherto beenavailable inthe art.

My invention contemplates, in general, constructing a device com lrisingan embossing roll or cylinder with a ternating series of cutting edgesand embossing dies arranged upon its periphery, and a pair of guideflanges on its ends, coperating with a plane roller or cylinder to feedan entire board between them continuously and firmly supported upon amoving carrier block, to simultaneously strip and pattern the same on`the cutting edges and embossing dies of the flanged roll.

In the accompanying drawings, I have.

shown a` device embodying my invention in its preferred form.

Figure l is an end view of the feed rolls showing a board between themresting on the carrying block; Fig. 2 shows a board planed and fluted asa preliminary step to being run through my machine; Fig. 3 is asectional view on line 3 of Fig. 2 Fig. 4 is a plan view of thecompleted product; Figs. 5 and 6 are sectional views in lines 5 and 6respectively of Eig'. 4;'Fig.' 7k is a sectional view on line 7 ofrFig.8; and Fig. 8 is a view partly in section and partly in plan of theembossing roller.

In the drawings, Aindicates a hollow roll or cylinder rotatively mountedupon a suitable frame, and provided with circular knife or cutting edgesc arranged at intervals about its periphery. The distance betweenadjacent knife or cutting edges determinesthe width of each strip to becut. At each end p of the roll a projecting circular guidel or flange ais arranged to guide the board and the wooden carrying lblock C. Oneither side of each of the cutting edges c are embossing dies d. Thesedies are made to impress any suitable pattern upon the adj-acent surfaceof the strips. The roll or cylinder A may be heated in any suitablemanner, various means adapted to this purpose being now in use in theart. Mounted beneath the roll A and cooperating with it, is a roll B,the two being adapted to feed or drive between them a wooden carryingblock C bearing on its upper surface the board to be stripped andpatterned. v

As a preliminary step the board may be planed and recessed so as tooutline the strips thereon (Fig. 2), the object of this step being topresent the board in better condition and save unnecessary wear upon theknife or cutting edges of the embossing roller A, though it may beentirely dispensed with in some cases and the Hat planed or unplanedboard, if sufficiently thin to be penetrated by the knives, run directlyinto the machine. The wooden carrying block C is adapted to support andfrictionally hold the board during progress between the rolls A and B,and prevent dulling or injuring the cutting edges c, which inpenetrating the board in the stripping'operation contact with it.-

The operation of my device is as follows: The board, planed and recessedlongitudinally to outline the strips, isplaced upon the Wooden carryingblock C and adjusted so that the recesses coincide with the planes ofthe cutting edges c. The rolls are then started to rotate in thedirection indicated by the arrows in Fig. 1, the thickness of the woodencarrying block being such that the board is pressed against the heatedsurface of the embossing roll. This crowding and feeding operationcauses the heated dies and cutting edges to stamp yand strip the boardfrom end to end, producing a number of nished strips smooth on thebottoms with raised or depressed patterns, according to the form of thetions will suggest themselves to those skilled I in the art, but

What I claim is:

The combination of upper and lower feed rolls cooperating to advance acarrying block and wooden board between them7 a carrying block adaptedto rietionally engage a wooden board laid upon it, end flanges on saidupper roll adapted to guide said blockI cire 5 eular cutting edges uponthe periphery of said upper` roll transversely of the axis 'thereofadapted to eut said board in strips and dies on either side of each ofsaid edges adapted to impress a pattern or design upon said 10 strips,whereby an entire wooden board is accurately and continuously guidedbetween said rolls and simultaneously embossed and out in strips.

In testimony whereof l hereunto :LHiX my signature in the presence oftwo witnesses.
